MACHINE FOR-BLOWING HOLLOW GLASS A IpL 'sQjf To a whom zit may concern:

Be it known that I, CORNELIUS J. NOLAN, a citizen of the United States, residing at To ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Machines for Blowing Hollow- Glass Articles, of which the following is a specification, reference being had therein to the accompanying drawings. The invention consists in the construction of a glass-blowing machine, and relates/particularly tomachines' designed for blowing hollow articlessuch, for instance, as incandescent-lamp bulbs-although it may be r5 used for other articles. v The invention consists in the construction, arrangement, and combination of the parts, as more fully hereinafter described, and particularly pointed out in the claims. In the drawings, Figure 1 is a side elevation of my'improved machine, a part ofthe framework and the tank being in section to more clearlyillustrate the construction. Fig.

2 is a section on line :1: a: of Fig. 1, showing the 2 5 operating parts op the base in plane. Fig. 3 is a rear elevationfpartly in section. Fig. 4 is a detail section illustrating the construction of the starting and stopping mechanism.

A is the base of the machine, in one side of 0 which is the-tank B, adapted to contain waterfor wetting the paste-lined molds between operations.

0' is the arch-bracket on the base and sprung over the inner edge of the tank. In 3 5 this bracket is supported a standard 0. To the standard are secured the brackets D and D, which support and guide the blow-iron E. At the upper end of the post is a bracket F, in which is slidingly secured a coupling F. 40 This coupling has secured to its'upper end the pinionG, to which the air-supply pipe G has a swiveled connection. This air-pipe connects with a passage or in the top of the post G, which in turn connects with a pas- 4 5' sage a, through a bracket or arm H, extending rearwardly from the post, and the passage in this arm connects with the air-supply under pressure from any suitable point, (not shown,) being through a valve d. The pinion G meshes with a gear-Wheel I, j'ournaled on the upper end of the post, which in turn is driven by a gear-wheel I on the upper end of the shaft. J, motion being imparted to this shaft in the manner to be hereinafter described. Y

' Y in the camwheel L.

which at their inner ends are pivoted upon a common pivot T on the outer end of the lever T, journaled at U in a bracket U on the frame. The other end of this lever, which is substantially a bell-crank lever T, isconnected by a connecting-rod V with a camway V in the cam wheel L, the connection being a roller-wrist which is supported. upon a lever The mold-sections have also connected to them links W, which have a universal-j oint connection with a sliding frame X, which is Qlldfid by and supported on the guide-rods f on the top of the frame. This frame is reciprocated by a connectingwod Y, having a. suitable roller-wrist engaging with a camway This connecting-rod slides through suitable guides 0 on the frame X and has a collar 1", adapted to en age one of these lugs and'with the spring 8 etween the collar and the other lug, so that the frame will be positively actuated in its inward movement and yieldingly in its return movement. This particular form of mechanism for operating the mold-sections is no part of my present invention.

The parts being thus constructed, their operation is as follows: The operator gathers the glass on the blowpipe E in the usual manner and places it in the brackets D and D, with the gathered glass suspended from the lower end.- At this time the mold-sections S are in their upper position and open. The operator depressing the lever S starts the machine in the manner described. As soon as the cam-wheel L starts to rotate the moldsections are closed about the glass on the blowpipe. Just before the sections are closed the valve-rod & is actuated by the small cam 76, which lifts the valve-rod and opens the valve for an instant, blowing a puff of air into the blank on the end of the blowpipe, expanding it to a size slightly smaller than the interior of the mold, which is then instantly closed about it. The molds being closed about the blank, as shown in Fig. 1, the camflange 7c gradually opens the air-valve, which allows the pressure to enter the article and blow it to the shape of the mold. All the time that the shaft M is rotating the coupler F, together with the blowpipe, will also be rotating through. the gear connection described. One of the earl T movements of the machine is the lowering o the coupler F onto the blowpipe by means of the lever J and the connecting-rod K, where it remains until the blowing is completed. When the blowing is completed, the air-valve will be closed, and

the cam will first open the mold-sections and then through the connecting-rod Vwill rock them in their op 11 position down into the waterin the tan B and back again to their for incandescent lamps, if the article is not expanded to nearly the size of the mold before the mold is inclosed about it and the air admitted for blowing it is apt to disfigure or scratch the blank during the blowing operation, and this I obviate by the use of the initial puff of air hereinbefore described. What I claim as my invention is 1. In a glass-blowing machine, the combination of an air-conduit leading to the article to be blown, of an air-valve in said conduit, and means for opening and closing the same to admit a limited quantity of air, and means for subsequently opening the valve for blow ing purposes, for the purpose described.

2. In a glass-blowing machine, the combinationof a sectional mold, means for opening and closing the same, an air-conduit leading to the article to be blown, an air-valve in said conduit, means for opening and closing said air-valve before the molds are closed, means.

for subsequently closing said molds and opening the valve to blow the article.

3. In a glassblowing machine, the combination of the air-conduit into the article to be blown, of means for admitting a limited quantity of air into the article and closing said conduit before the final blowing operation.

4. In a glass-blowing machine, the combination of a sectional mold, means for opening and closing the mold, an air-conduit leading to the article to be blown, avalve in said conduit, means for opening and closing said valve before the moldsare closed, means for closing themold therea ter and means for gradually opening the valve subsequent to the closing of the molds. v

5. In a glass-blowing machine, the combination of a supporting-frame, a reci rocating coupling-nozzle, a support for the hlowpipe, means for rotating the coupling-nozzle, a sectional mold, an air-supply leading to thenozzle, a valve therein, a driven shaft, a single cam-wheel thereon and cam-bearings on said wheel for reciprocating said coupling-nozzle, actuating said air-valve, and reciprocating and opening and closing said molds.

In testimony whereof I aflix my signature in presence of two witnesses.
